Hi,
I have a file containing one TH1F that takes a lot of time to load, and displays
a black bar at the left side of the histogram. It contains ~1.2 million entries
and most of them are in the overflow bin.
The code that fills this histogram was done by someone else, but I checked it
and it looks fine, it does not even use labels for the axis, so I don’t know
where this black bar comes from.
I attach the root file that contains the histogram.
Thanks in advance for any help on what could be the problem.
